Abstract: ROTARY ENGINE COOLING SYSTEM  Abstract of the Disclosure A rotary engine has a substantially trochoidal-shaped housing cavity in which a rotor planetates.  A cooling system for the engine directs coolant along a single series path consisting of series connected groups of passages.  Coolant enters near the intake port, passes downwardly and axially through the cooler regions of the engine, then passes upwardly and axially through the hotter regions.  By first flowing through the coolest regions, coolant pressure is reduced, thus reducing the saturation temperature of the coolant and thereby enhancing the nucleate boiling heat transfer mechanism which predominates in the high heat flux region of the engine during hig power level operation.

Abstract: HYDROXYALKYL CARBAMATE-CONTAINING RESINS FOR CATHODIC    ELECTRODEPOSITION AND METHOD OF MAKING THE SAME                    ABSTRACT A cathodically electrodepositable, self-cross-linkable polymer is a hydroxyalkyl carbamate-containing resin having at least one tertiary amine and at least two hydroxyalkyl carbamate groups per molecule. The polymer is made by reacting an epoxy resin having an  average epoxy equivalent weight of from about 300 to about 10,000 with one or more amines having at least one secondary amine group and at least one hydroxyalkyl  carbamate group or precursor thereof.  Hydrophobic amines may be co-reacted to enhance hydrophobicity of the polymer. An electrodeposition bath is made by acidifying the polymer to form an aqueous disper-sion. A low temperature-curable coating is attained by utilization of the polymer with a suitable quaternary or ternary compound catalyst.

Abstract: SILK SCREEN ROLLER APPLICATOR TECHNIQUE            Abstract of the Disclosure Silk  screen  roller  applicators,  employed  in  a process which is also known as Screen Process Printing, are often used in the printing of labels and other materials.   The present invention involves joining the edges of silk screen type material along a very narrow line, such as 1/32 inch, so that economies are achieved in printing and the associated use of paper, when the resultant applicator is formed.  The two edges to be joined are each marked with at least two index marks, and these are aligned with corresponding light slots which are located on a base on either side of a fusing line. The silk screen type mesh which may be formed of a polyester  coated  with  nickel,  may  be  held  down  by magnetic plates, and the edges are accurately overlapped by aligning the index marks and the light guide slots, through the use of eccentric or similar mechanisms.   A thin thread of nylon or other fusible material is tightly drawn between the edges of the fabric along the fusing line, with the fabric overlapped by about 1/32 inch.  A pre-heated fusing bar is briefly lowered along the fusing line and promptly raised, after fusing the thread into the pores in both of the two edges of the silk screen type material.

Abstract: ABSTRACT OF THE DISCLOSURE         A  microfinishing   apparatus   and  method   is   disclosed particularly useful for microfinishing workpiece surfaces such as are found in journal bearings and cylinder bores. This invention improves over conventional machines and methods wherein coated abrasive tape is brought into contact with a relatively rotating workpiece surface and is pressed  against  that  surface  by  an  elastomeric  plastic  insert.         According to this invention, the insert is made from a relatively rigid substance such as honing material stone.  Since the insert is made from a rigid material, the insert surface shape is generated in the workpiece surface and therefore geometry corrections in the workpiece surface can be accomplished.  In alternate embodiments of this invention, the rigid inserts have relieved portions or noncylindrical surfaces such that a desired surface profile in the workpiece surface is generated.   In another embodiment, one or more flexible inserts are added to the rigid insert enabling the fillet radius area to be microfinished. In yet another embodiment, coated abrasive tape includes a multiplicity of perforations thereby permitting the exchange of cutting fluids between the surfaces.  Finally, several means for supporting the rigid inserts for slight rotation relative to the workpiece surface are described.

Abstract: ABSTRACT OF THE DISCLOSURE        A loaded magazine for an insertion machine comprises a receptacle having parallel spaced side wall portions, a plurality of horizontally directed, vertically displaced, parallel channels formed in the opposed surfaces of the side wall portions, each channel of a respective side wall portion being aligned with a channel of the other side wall portion, a multiplicity of electronic components disposed within the magazine, the components including a central body portion and lead portions extending axially beyond the opposed ends of the body portion.  The body portions of the components are disposed between the walls, and the lead portions of the components extend laterally beyond the walls into the channels to thereby slidably support the components in a series of horizontal rows, each row being vertically spaced from the next adjacent row as a result of the vertical displacement of the channels.  The magazine is capable of rapidly and accurately removing electronic components from a bulk storage supply, forming the component leads into a parallel spaced configuration necessary for insertion into a P.C. board, advancing the lead-formed component into a position within the P.C. board, stripping the component from the insertion mechanism and reloading a further component into the insertion mechanism.
